  • the remaining liquids are extremely difficult to be cleaned during a manufacturing process, and the remaining liquids such as oxidized and discolored inside respectively in the first passage ( 13 ) and the second passage ( 14 ) are ejected at the time of injection for first use, so that the remaining liquids are undesirable from a viewpoint of a product value even though the remaining liquids does not cause the hardening or defective injection of the aerosol content.
  • the stem ( 11 ) is composed of a movable seal member ( 28 ) arranged with the second seal member ( 17 ) and the first seal member ( 25 ), and a passage member ( 29 ) disposed with the second passage ( 14 ) and the first passage ( 13 ).
  • the passage member ( 29 ) is set to detachable from the housing upon separated from the movable seal member ( 28 ), while the second seal member ( 17 ) is disposed at the outer circumference of the movable seal member ( 28 ) and is arranged above the second communicating opening ( 24 ) at the time that the movable seal member ( 28 ) is not pressed.
  • the second seal member ( 17 ) is moved up to the portion lower than the second communicating opening ( 24 ) in association with the pressing of the movable seal member ( 28 ), while the first seal member ( 25 ) is connected closely, where the movable seal member ( 28 ) is pressed, to the inner circumferential surface of the housing ( 7 ) at the interval between the first communicating opening ( 23 ) and the second communicating opening ( 24 ) to intercept the communication between the first liquid and the exterior of the container, while the side opening ( 12 ) and the first liquid are communicated as connectable at the time that the movable seal member ( 28 ) is pressed.
  • the passage member ( 29 ) is detached from the housing ( 7 ) and subsequently a filling nozzle ( 31 ) is inserted in the housing, so that both or either the first and second liquids are filled upon pressing the movable seal member ( 28 ), while when distributing the first and second liquids to the exterior of the container, the passage member ( 29 ) is inserted into the housing ( 7 ) to be communicated with the movable seal member ( 28 ).
  • the passage member ( 29 ) is detached, when filling the aerosol content, to communicate the filling nozzle ( 31 ) with the movable seal member ( 28 ) as shown in FIG. 11 , thereby filling the aerosol content, so that the aerosol content does not come in contact with the second passage ( 14 ) and the first passage ( 13 ). Therefore, the discoloration conventionally caused due to the oxidation of the remaining aerosol content does not occur in the aerosol content, so that the product value can be improved. Furthermore, an example for filling the aerosol content, as shown in FIG.
  • FIG 11 shows a state where the aerosol content is filled in the first internal bag ( 5 ), in which the aerosol content is filled in the second internal bag ( 6 ) subsequently after the first internal bag ( 5 ) is completed to be filled. While, the aerosol content may be filled into the first internal bag ( 5 ) and the second internal bag ( 6 ) at the same time.
  • a communicating passage ( 32 ) between the second communicating opening ( 24 ) and the second liquid and a communicating passage ( 33 ) between the first communicating opening ( 23 ) and the first liquid are formed without disposed with any special valves or the like, however, in the different seventh embodiment as shown in FIG. 10 and FIG. 11 , the filling open valve ( 34 ) such as released with filling pressure only when filling the second and first liquids, is arranged at each of the communicating passage ( 32 ) between the second communicating opening ( 24 ) and the second liquid and at the communicating passage ( 33 ) between the first communicating opening ( 23 ) and the first liquid.
  • the filling open valve ( 34 ) is formed at each of the inner surface of the communicating passages ( 32 ), ( 33 ) via a hinge part ( 35 ), and is constituted as in a close contact with each valve seat of the communicating passages ( 32 ), ( 33 ) with the pressure of propellant, however, when filling the aerosol content with high pressure, the filling open valve ( 34 ) is released from the hinge part ( 35 ) to enable the aerosol content to be filled at high speed, as shown in FIG. 11 .
  • such a passing small opening ( 36 ) is formed to the filling open valve ( 34 ), as passing the second and first liquids at the time of distribution of the second and first liquids.
  • this passing small opening ( 36 ) the aerosol content can be prevented from excessively supplied to the second passage ( 14 ) and the first passage ( 13 ) when distributed, thereby being able to prevent the injected aerosol content from dripping or having enlarged particles.
